Practical Reason and Norms: Updated Edition - Tapa blanda

"This book is a sophisticated contribution to modern analytical jurisprudence, providing an analysis of structures of reasons-particularly the idea of `exclusionary reasons'-which lays a basis for an account of normativity. Raz's book also builds on, criticizes, and develops thoroughly the idea of the `internal aspect' of rules in Hart's The Concept of Law. Anyone working in the area of jurisprudence, or in the analysis of norms and obligations generally, simply cannot proceed without taking into account Raz's ideas."-Jeremy Waldron, School of Law, University of California, Berkeley

Essential for scholars in moral, legal, and political philosophy, this book makes possible a more fundamental analysis of rules than has been previously attempted, by introducing the novel notion of second order reasons. The author applies this new analytic framework to such normative concepts as decisions, commands, authority, and supererogation, and shows that these concepts are similarly explicable in terms of reasons of different levels. Finally, the analysis of rules serves as the basis for an examination of various forms of normative systems--especially games and legal systems.
